I converted a miele as well (see link in my sig). Ask for bmx chainring bolts from your lbs. In regards to cable stops, I used a grinder to take them off. Wasn't pretty and I got a bit of the frame in one spot. I ended up keeping the downtube shifter bosses. ILm looking for a new frame/complete bike anyways but the miele conversion has been good to me for the last few years.
